Antinatalism

Anti-Natalism is the general or universal belief that there is negative value to procreation.

While there are usually specific cases where sensible people are anti-natalist, like during wars, that in itself is not anti-natalist. Likewise, vegans are usually anti-natalist with respect to farmed animals and believe breeding these animals for a life of suffering and an early death is wrong, again that is in itself not anti-natalism.

Anti-natalists do not have objections merely to specific cases of procreation where inordinate harm is involved, but to procreation generally even from healthy, secure, well adjusted parents.

The claim, as many broad claims are, is typically deontological (or dogmatic) in nature and not founded on consequentialistic reasoning that considers exceptions. There are consequentialist anti-natalists, but usually of a special negative variety (based on bind adherence to claims like Benatar's Asymmetry).

Benatar's Asymmetry

Unsubstantiated assertion that the absence of pain is good, but the absence of pleasure is not bad

One of the Bad Arguments for Veganism Benatar's asymmetry claims on intuition that the absence of pain is good, but the absence of pleasure is not bad.

This is related to negative utilitarianism, although he doesn't deny the positive value of pleasure during existence as negative utilitarians do.

Existence Bias

An unfalsifiable claim that we are biased about our own existence, so we're perpetually in error when we assess that we enjoy life and generally are happy about having been born.

Consent to Exist

The deontological claim that acting on another without consent is always wrong, and that because a non-existent being can not consent to come into existence creating a sentient being is always wrong.
